To all whom, it may concern:

. Be it known that I, JOSEPH A. Ross, acitizen of the United States, anda resident of Elgin, in the county of Grand and State of Utah, haveinvented a new and Improved Combined Door Holder and Buffer, of whichthe following is a full, clear, and exact description.

The object of this invention is to provide a novel simple door-holdingdevice which may be instantly converted into a buffer adapted forcontact with awall when the dooris swung open, and thus prevent injuryto the door and wall.

'The invention consists in the novel construction and combination ofparts, as is hereinafter described, and defined in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views.

Figure 1 is a perspective view showing the device applied upon a doorand adjusted for holding the door in a partly-opened position byenforced contact with the floor. Fig. 2is an edge view of a door inpart, a portion of a wall toward which the door is held to swing,

and the improvement carried by the door having the working parts thereofadjusted to serve asa buffer, shown in contact with the of the lowerportion of a door, the device be: ing shown adjusted to hold the door byits pressure on the floor, the section being substantially on the line 330f Fig. 1. Fig. 4 is a partly-sectional plan view of the parts shown inFig. 3, substantially on the line 4 4 in said figure. Fig. 5 is anenlarged side view of a rockable lifting-arm and a sectional side viewof a fragmentary portion of a door whereon said lifting-arm is pivoted.Fig. 6 is a front view of the lifting-arm, seen in direction of thearrow in Fig. 5. Fig. 7 is a perspective view of awasher-plate employed,and Fig. 8 is a vertical transverse sectional view substantially on theline 8 8 in Fig. 3.

A principal feature of the improvement consists of a pressure-block 10,of elastic material, such as vulcanized gum, preferably triangular incontour and having a plurality of spaced transverse channels a formed ineach side of the angular periphery. Centrally in the pressure block 10 atransverse perforation is formed, wherein a lining-sleeve b is closelyfitted, affording a bearing for the block to turn on. In the sleeve 6 isloosely fitted a pivot-shaft 11, which projects at each end therefrom.

A bracket-arm 12 is provided, having side arms 12 thereon, which projectin advance of the flat body of the arm, said projecting ends having eacha perforation, these opposite perforations engaging loosely respectiveends of the pivot-shaft 11, that is furnished with a head on one end,and in the opposite end, that projects through an arm 12", acircumferential groove is formed, the use of which will hereinafterappear.

A bracket-plate 13 is adapted for rockably holding the bracket-arm 12 onthe lower portion of a door and comprises a flat plate having atransverse hook member 13 formedon its normally lower end. Aslot-opening c is formed centrally in the bracket-plate 13 above thehook formation 13, and screw-holes are formed therein each side of theslot to enable the screwed attachment of the bracket-plate upon a door Anear its free side edge and lower edge thereof, as shown in Fig. 1.

Upon the end of the bracket-arm 12 opposite from the side arms 12 anupturned hook member-12 is formed, which loosely engages with the hookformation 13, as. is clearly shown in Fig. 3. On the side edges of theslot 0 in the bracket-plate 13 similar guides c are formed by rabbetingsaid edges, and on these guides ends of a roller 0 may be seated for arolling engagement therewith. A slot d is longitudinally formed in thebracket-arm 12 at its transverse center, and about at the center oflength of said slot a cross-bar OZ is formed or secured above the slot.

An essentially U-shaped plate-spring 1 1 is passed at its respectiveends through the slots 0 and ol, the bowed portion of the spring bearingagainst the hook member 12 and the slightly-curved ends of the springrespectively bearing upon the roller 0 and the cross-bar OZ, whichadapts the tension of the spring to press the block 10 toward the floorA of a room into which the door A swings.

The faces of the sides of the block 10 may be further roughened bygrooving them longitudinally or at right angles to the grooves a, thusadapting each side of the block that may be lowermost to frictionallyengage the floor or a covering thereon and hold the door stationary atany desired point of opened adjustment.

At a suitable distance above the lower edge of the door A, on the stilethereof which forms the free edge portion, a lifting-arm is pivoted,said arm being mainly fiat in the body, having a limb projected inopposite directions from a nearly circular-edged central portion 15,that is centrally perforated for the reception of a pivot-screw 6.

Upon one side edge of one limb 15 a wing e is turned at a right anglethereto and normally projects outward from the door, and

, said wing is disposed radially opposite the is employed, and, as isclearly shown in Figs.

5 and 7 the washer-plate is mainly flat and circular on the edge, withthe exception that a locking-toe f is out free on the edge of the washerand near it, thus permitting the toe to be bent at a right angle fromone side of the same, as appears in Fig. 7.

At a selected point on the door-stile the Washer-plate 16 is positionedby embedment of the toe f in the stile, as appears by dotted lines inFig. 5, and the pivot-screw e is screwed through alined perforations inthe lifting-arm portion 15 and the washer-plate, which will permit thefree turning movement of the lifting-arm. Each wing e 0 may be convexedon its edge and have an opening t' therein.

A lifting-rod 17 is furnished for connecting the lifting-arm with thebracket-arm 12. To this end a ring-eye b is formed on one end of thelifting-rod, which is loosely engaged within the groove in one end ofthe pivot-shaft 11, the normally upper end of the lifting-arm having asimilar ring-eye thereon, which is loosely engaged with a journal 71,that is formed in the edge portion of the wing e, as is shown in Figs. 5and 6.

It will be seen in Figs. 5 and 6 that the distance between thepivot-screw e and the point of journaled connection 11 between theliftingrod and the lifting-arm provides a crank which when turnedupwardly raises the rod 17 adistance equal to the throw of said crankand of course correspondingly raises the block 10 from the floor A.

In use it will be seen that upon turning the lifting-arm member 6'uppermost the bracketarm 12 will be rocked upward at its outer end andthe pressure-block 1O correspondingly elevated from the floor againststress of the spring 14, and as the wing e is at one side of the directline of draft had by the lifting-rod 17 the upper end of the latter willbe carried slightly to one side of said line of draft, resting againstthe wing 6 that is lowermost, and this will temporarily lock the rod andliftingarm in the position shown in Figs. 2, 5, and 6.

When the device is adjusted so as to release the pressure-block 10 fromthe floor A, the door may be freely swung toward the upright wall A andthe block 10 have contact therewith, the block turning so that one sideof the same will rest as a bufler against the wall and hold the door Aso removed as to prevent injurious contact, this appearing clearly inFig. 2.

From the foregoing description and by inspection of the drawings it willbe obvious that the improvement when applied upon a door may at any timeafter the door is opened be set to hold the door at any point ofswinging adjustment by a slight turning movement of the lifting-arm, soas to permit the stress of the spring 14 to throw the block 10 downwardand into contact with the floor A, the liftingarm then being disposed,as shown in Fig. 1, with the limbs thereon nearly horizontal.Furthermore, for releasing the block 10 from the floor a slight liftingmovement applied upon the wing a will rock it into an upright positionand through the rod 17 raise the bracket-arm 12 and block 10, as ishereinbefore fully explained.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. In a door holder and buffer, the combination with aspring-pressed arm held rockably on a door near its lower edge, and apressure-block on the outer end of said arm, of a lifting-rod looselyconnected by one end with the spring-pressed arm, and releasable meansfor holding the rod raised and the arm rocked upward.

2. In a door holder and buffer, the combination with a spring-pressedarm held rockably on a door near its lower edge, and a pressure-block onthe outer end of said arm, of alifting-rod loosely connected with thespring-pressed arm, and a lifting-arm pivoted upon the door above saidspring-pressed arm, the upper end of the rod having loose engagementwith the lifting-arm a distance from its pivot.

3. In a door holder and buifer, the combination with a spring-pressedarm held rockably on a door near its lower edge, and an elastic angularblock pivoted upon the outer end of the rockable spring-pressed arm, ofa lifting-rod loosely connected with said arm, and a lifting-arm pivotedupon the door above the spring-pressed arm, the upper end of thelifting-rod having a loose engagement with the lifting-arm a distancefrom its pivot.

1. In a door holder and buffer, the combination with a bracket-platesecured on a door near its lower edge, a spring-pressed arm hinged uponthe lower end of the bracketplate, and an angular elastic block pivotedupon the outer end of the spring-pressed arm,

cured upon a door near its free edge and lower edge, a bracket-arm alsohaving an opening, and a hook on the rear end that hingedly engages thehook on the bracket-plate, and a plate-spring having a substantially Ushape and passing at its ends respectively through the opening in thebracket plate and the bracket-arm, said spring normally pressing the armdownward, of a block on the outer end of the bracket-arm, and means forraising and releasably holding the block raised from the floor to serveas a buffer at a side wall.

6. In a door holder and bufler, the combination with a bracket-platehaving an opening therein and a transverse hook on the lower edge, saidopening having guides formed on its side edges by rabbeting said edges,and a roller the ends of which may seat and roll on the guides, of abracket-arm having a hook engaging the hook on the bracket-plate andalso having an opening and a cross-bar over the opening, a bentplate-spring passing at its ends through the openings in the bracketplate and arm, said ends respectively seating upon the roller andcross-bar, thus adapting the spring for the depression of thebracket-arm, and an angular block pivoted on the outer end of thebracket-arm.

In testimony whereofl have signed my name to this specification in thepresence of two subscribing witnesses.

JOSEPH A. ROSS.
